Matthew Morrison and Neil Patrick Harris Photo

From: Photo Flash: Neil Patrick Harris on GLEE!

Neil Patrick Harris will be playing a former rival of Mr. Schu (Matthew Morrison) who's come back to town to try to shut down the show choir. Reports Entertainment Weekly: 'Harris and on-screen rival Matthew Morrison will find themselves up for the same role in a community theater production - hence the 'Dream On' duet/showdown [that had been] teased in Ausiello TV.'
